not be making a return appearance in Marvel vs. Capcom 3. You may also have heard that no more members of the Darkstalkers cast would be joining the roster. You might be inclined to believe these statements because they came from the mouth of Capcom's Ryota Niitsuma himself.
Either Niitsuma was misinformed or someone was fibbing. Regardless, here are some videos of Hsien-Ko and Sentinel in Marvel vs. Capcom 3. Hsien-Ko, incidentally, was among the characters mentioned on a purportedly leaked list we posted last year. Sentinel was not, though the this isn't the first time we've seen an unlisted character pop up.
